VAGUUM-CLEANEE-HANDLE SWITCH.

Application filed June 9,

To all whom it may concern Be it known that I, IRA R. SELTZER, a citizen of the United States, residing at Waterbury, in the county of New-Haven and State of Connecticut, have invented a new and useful Improvement in Vacuum- Cleaner-Handle Switches; and I do hereby declare the following, when taken in connection with the accompanyingdrawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Fig. 1 a broken, a plan view of a vacuumcleaner handle equipped with my improved switch.

F ig. 2 a detached, plan view of the switchmechanism.

Fig. 3 a View in side elevation of the switch-mechanism, with the vacuum-cleaner handle in longitudinal, vertical section.

Fig. i a reverse, plan view of the switchmechanism with the handle in longitudinal, horizontal section.

Fig. 5 an end view-of the switch-mechanism, with the handle in transverse section.

Fig. 6 a view of the mechanism and handle in longitudinal section on the line 6-45 of Fig. 1.

Fig. 7 a view thereof in transverse section on the iine 7-7 of Fig. 3.

Fig. 8 a detached, underside, perspective view of the operating-slide.

Fig. 9 a modified form of any improvement, in which the switch-mechanism is mounted in a transversely-bowed plate ex tending over an opening in the handle.

My invention relates to an improved vacuum-cleaner handle-switch, the object being to produce a compact and efficientslide-operated snap-switch constructed with particular reference to convenience of operation, as well as observation as to its operative position.

lVith these ends in view, my invention consists in a vacuum-cleaner handle-switch having certain details of construct-ion and combinations of parts as will be hereinafter described and particularly pointed out in the claim.

In carrying out my invention, as herein shown, T employ an oblong, substantially rectangular, slide comprising a metal plate 1923. Serial No. 644,331.

10 having an upstanding operating-boss 11 located midway of its length and formed at its sides and ends with depending and inwardly-bent mounting-fingers 12, by which it is clasped upon an insulating body 13, to which it conforms in shape. The respective forward and rear ends of the plate provide surfaces for the imposition upon them of the words Off and On, as clearly shown in Fig. 2, these words being lohollow handle 15 and secured to the underface of the upper surface thereof by means of screws 18. The slide-body 13 is formed midway of its length with a socket-hole 19, receiving an operating-arm 20 forming an extension of the upper end of the actuator 21 of a snap-switch mechanism of standard construction, the said actuator being mounted for oscillating movement upon a pivot 22 and engaging with and operating a contact-member 23 having contact-ears 24 respectively engaging with spring-contacts 25 and 26, respectively connected, in turn, with terminals 27 and 28 carried by the frame 17, from which they are suitably insulated. The said contact-member 23 is formed with an arm 29 encircled by a helical operatingspring 30 and having sliding and rocking movement in a hole 31 formed in a plate 32 installed within the frame 17, from which it is suitably insulated.

As shown, the contact-member 23 is in its open-circuit position, but it will be understood that by moving the slide 13 forward, the actuator 21 will be rocked, so as to lift the contact-member 23, and then bring its cars 24 into engagement with the contactsprings 25 and 26, whereby a circuit is completed between the two terminals 27 and 28 of the switch and indicated by the exposure of the word On through the slot 14 in the tubular handle 15.

In the modified construction shown by Fig. 9, the switch-mechanism is secured, at its ends, by screws 33, to the ends of a trans- Versely-bowed plate 34 fastened by the said screws 33 to thehandle 35, the upper surface of which is formed with an opening sufi'iciently large to permit the switch-frame 17 to be maneuvered into the interior of the handle. In this construction, a slot 36 is formed in the plate 34 for the upward projection through it of the boss 11, instead of in the handle itself, as in the construction previously described.

I claim:

In a vacuum-cleaner handle switch, the combination with a hollow vacuum-cleaner handle, of a snap-switch mechanism located therein and comprising a sheet-metal frame formed with a shallow recess having side walls parallel with the axes of the handle and frame, and a removabl slide located within the said recess in which it is guided in its longitudinal movement, and comprising a body of insulating material removably connected with the snap mechanism for the actuation thereof and also comprising a metal plate applied to the said insulating body and formed with a boss projecting through an opening in the said handle at a point between the attachment of the ends of the said frame thereto, whereby the said projection is insulated from the switch mechanism.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

IRA R. SELTZER.
